7Z The Andamans and Nicobars. — V. Ball. 



the secondaries and tertiaries washed with yellowish-olive. 

 The coverts of the primaries are always tipped with 

 yellow, producing a slight spot of this hue, which does not 

 occur, at least, in the adult male of 0. Ckinensis. Younger 

 males have, as usual, the back and wings tinged with dusky- 

 greenish ; and in females (and perhaps still younger males) 

 tha same dull colour prevails on the head and neck ; the broad 

 occipital crescent is merely indicated; the feathers of the under 

 parts have each a black central stripe, and the tail is wholly 

 dusky -yellowish above, prevailing throughout the outer webs 

 of all the feathers, while the inner webs are successively more 

 deeply terminated with yellow, this color being alone seen 

 underneath in adults of both sexes. Length about 11 inches 

 or rather more j wing 6 ; tail 45 — 5; bill to gape 1"5 ; tarsus 

 1 mch.."—Bl^th. 



Peculiar to the Nicobar Islands, a specimen shot by me on 

 Nancowry had the following dimensions : — wing 5*75 ; tail 4'75 ; 

 bill at front TS ; tarsi I'l.

Mb. Blyth's description of the Andaman Oriole is as follows : — 

 " Has no yellow at all on the secondaries and tertiaries beyond a 

 small yellow spot tipping the latter, and a slight yellowish- 

 white margin to the former. Colour of male brilliant yellow, with 

 the nape-mark, wings beyond the coverts of the secondaries 

 and a portion of the tail, deep black. The female has a dusky- 

 ish tinge on the mouth, and the exposed portion of the black 

 part of the wings is tinged with green, as also the middle tail- 

 feathers for the greater portion of their length. Middle tail- 

 feathers in both sexes slightly tipped, and the rest successively 

 more so, to the outermost, with bright yellow. Bill carneous and 

 legs plumbeous, as usual in the genus. Wing 5 j ; tail 3| ? (mis- 

 printed 9|) ; bill to gape If. In colouring, this species resembles 

 0. macrourus of the neighbouring group of the Nicobars, but 

 it is smaller, with narrower nape-mark and proportionally 

 shorter tail, which last is commonly 5 inches in 0. maa-ourus" 



Specimens of this bird, recently examined by me, had the 

 following measurements : — 



Length 88 ; wing 5'3 ; bill at front 1 ; tarsus "9 ; tail 335 inches.
